Whiteline rear camber kit is around $120-$150
Whiteline front camber kit is around $130-$170
Whiteline front castor kit is around $100-$120
So really it shouldn't be more than $500
I got all mine for around $340. Ring up an Autobarn or something near you, give them the part numbers (KCA348, KCA331, KCA347), ask what the best price they can give for all three. Autobarn do a 10% off RACQ discount so ask for that after. Definetely can get them for less than $650. Your call.
